Method Detail

copyFile

public void copyFile(File in,
                     File out)
              throws IOException

Copies a file using NIO

Parameters:

in - The source file

out - The destination file

Throws:

IOException

createFileWithPath

public static File createFileWithPath(String path)
                               throws IOException

Returns a file with the given path, which is guaranteed to exist on return

Parameters:

path -

Returns:

Throws:

IOException

openTextFile

public static BufferedReader openTextFile(File f)
                                   throws FileNotFoundException

Throws:

FileNotFoundException

getFileForWriting

public static PrintStream getFileForWriting(File f)
                                     throws FileNotFoundException

Throws:

FileNotFoundException

forceTrailingSlash

public static String forceTrailingSlash(String str)

Adds a trailing slash to a directory path string if and only if the path string does not already end with a trailing slash. This ensures that a filename appended to the end of the string will function as a filename and not an invalid directory name.

Parameters:

str - The path string

Returns:

The path string guaranteed to end with a slash

forceLeadingDotSlash

public static String forceLeadingDotSlash(String str)

Adds a leading ./ to a file path string if and only if the path string is not an absolute path. This is necessary for relative paths that contain only one file if the getParentFile() method of File class is to work properly.

Parameters:

str -

Returns:

isAbsolutePath

public static boolean isAbsolutePath(String str)

Determines whether a path string is a relative or absolute path.

Parameters:

str - The path string to be analyzed

Returns:

True iff the file is a UNIX, DOS, or Windows absolute path

getFilesWithExt

public static File[] getFilesWithExt(File root,
                                     String ext)

Get files having extention

Parameters:

ext - e.g. ".txt"

Returns:
